\ OTTO H. WENDERO'IH, OF NEW YORK, N. Y.

GAS-HOLDER.

To all whom it may concern:

Be it known that I, OTTO H. VVENDEROTH, a citizen of the United States, and a resident of New York city, in. the county of New York and State of New York, have invent-ed certain new and useful Improvements in Gas-Holders, of which the following is a specification.

My invention relates to gas holders, and the objects of my invention are to provide a holder from which no gas can leak by reason of a break in the water seal; to control the admission of the gas thereto and its withdrawal therefrom; to provide means by which the water chamber may be conveniently filled, and a gage to show the height of water in the water seal; and to prevent an excessive pressure of gas from forcing the part of this specification, Figure 1, is a plan view of my improved gas holder, the outer shell being shown in cross section on line m-m of Fig. 2. Fig. 2, is a vertical sectional view of a gas-holder embodying my inven tion, showing the inlet valve open and outlet valve in closed position. Fig. 3, is a verti- I cal sectional view showing the inlet valve closed and outlet valve open. Fig. 4c, is a perspective view of a portion of the valve mechanism. Fig. 5, is a sectional view of the outlet valve and spring.

A, indicates the outer casing which comprises bottom A, a side wall A and a top A and connected thereto is an inner circular wall A between which and the wall A is formed an annular water chamber B which serves as a seal to prevent escape of gas from the chamber G. The cover or top A .is connected to the wall A by bolts D,

which pass through laterally extending flanges E and E which are fastened to the side wall A and cover A respectively, as shown. By removing the bolts the cover may be easily removed.

Specification of Letters Patent.

Serial No. 523,855.

F, indicates a bell, comprising a cover F which is provided with a hole F in which it is closely fitted to and connected with a rod G, which extends upward through a hole A in the cover A and is guided therein. The lower edge of the bell extends downward into the annular water chamber B in the usual manner. Extending upward about the same distance from the bottom into the chamber C, are two pipes H and I. The lower ends of these pipes are screwed into flanged couplings H and I, respectively, the flanges of which are connected to the bottom A, as illustrated, the lower ends of the couplings extending through the bottom of the casing, and being threaded to receive the pipes H and I respectively.

The rod G carries at its lower end, a guide comprising two flat strips J and J which are riveted or bolted together, and are bent at each end to form a hemicircle to conform to the curve of the pipes H and I, the pipes serving to guide the rod G and thereby guide the bell F and valves K and L, the upper end of the rod G being guided in the hole A v in cover A as will be readily understood.

A cross piece M is connected to the valve K at one end and carries valve L at its opposite end. The valve K consists of a tube, closed at its upper end, and fitted to slidingly engage the inner wall of pipe H. It is provided with an opening K, which registers with an opening H in the pipe II when the bell F is in its lower position, and said opening H is closed by the lower end of pipe K, when the bell is in its highest position as illustrated in Fig. 3. The valve L closes the pipe I when the bell is near its lowest position only, the top of pipe I serving as its valve seat. The valve L is provided with a valve stem L which projects through and is freely movable vertically in .a hole I and a cross pin L prevents the valve stem from dropping from the cross piece when lifted from its seat. A light spring L may be used if desired to prevent lateral swinging of the valve.

A spring N is located between the top of the bell and underside of cover A so that the gas pressure will slightly increase in chamber C as the bell is raised thereby, to insure amaximum gas pressure in starting an engine taking its supply from the holder. This spring may be omitted if desired.

A water gage O, is provided to indicate the height of water in the chamber B.

A funnel P is provided and fastened to casing A and the casing is provided with a hole at P which opens into chamber B, so that the sealing fluid may be conveniently introduced therein.

Q, indicates water in chamber B.

The operation is as follows: Gas entering chamber C from pipes H and H, under pressure, and being prevented from escaping by water seal Q and valve L, raises bell F, thus opening valve L and permitting gas to flow through pipe I to the source of consumption, which we will assume to be a gas engine. e will also assume that gas is being supplied for lighting purposes, from the same gas main supplying the gas-holder. The gas pressure will raise bell F until the spring N is compressed far enough, taken with the weight of the bell and parts connected thereto, to balance the normal gas pressure, the water rising in the annular space R and being lowered in the annular space S, a certain degree, depending on the pressure, as usual in gas-holders. The engine now being started, the gas will flow di; rectly through the holder and supply the engine, but should the gas supply in the main be unable to supply the engine, the bell would gradually fall until valve L would close, thus preventing the suction from the engine from drawing the water from the seal. Now should the gas pressure grow excessive in the main, the bell will rise far enough to close the opening H thus preventing the excessive pressure from forcing the water from the seal. Should lights be burning, supplied by gas from the main, and the engine should use more gas than that at which the normal pressure could be maintained, the bell would drop, closing valve L, thus stopping the engine, but maintaining the gas pressure on the main, so that the lights would not be extinguished. Therefore, my construction acts as a safety device, since if the gas pressure were lowered far enough, the lights supplied from the main would be extinguished and if the engine were stopped, gas would again raise to normal pressure in the main and flow, unlighted, into rooms, etc., causing great danger.

Having thus described my invention what ,I claim as new and desire to secure by Letters Patent is,

1. A gas holder comprising an inclosing casing, a bell contained therein, inlet and outlet pipes, a rod having a guide at one end engaging with said pipes, its other end extending upward through the top of said bell and the cover of the casing, said bell being attached to said rod and guided thereby.
